I've got a '96 5.7 Suburban with 140k miles. I bought it last fall in Utah and drove it to Kentucky. Before the trip I checked the coolant level in the radiator and it was low, so I added some to bring it up to full. The overflow was full then, and has been full ever since, even after the long road trip.
I'm now having problems with low radiator levels and overheating and occassional small puddles on my garage floor. Can't tell exactly where the leak is, but it's dripping under the general area of the overflow.
If my overflow is plugged, will the pressure cause the coolant to leak from the overflow hose? That's my guess. And shouldn't the coolant flow freely from the overflow back to the radiator if the radiator cap is off, which it doesn't, even if I put my mouth over the overflow opening and blow (Don't worry, I take full personal responsibility for any toxic coolant I ingest)? :rofl:
Thanks for any help!
